Scientists Discover Stinging Truths About Jellyfish Blooms in the Bering Sea
A new study helps explain a cyclic increase and decrease of jellyfish populations, which transformed parts of the Bering Sea--one of the U.S.'s most productive fisheries--into veritable jellytoriums during the 1990s. The study shows the availability of food for jellyfish may cap the potential size of the Bering Sea's jellyfish population, even while other factors, such as rising temperatures, may encourage the population's continued growth. A special report, "Jellyfish Gone Wild: Environmental Change and Jellyfish Swarms," reveals more of what we are learning about jellyfish.

Plastic Brain Outsmarts Experts
Can you study for an IQ test? Swiss postdoctoral fellows working at the University of Michigan in Ann Arbor suggest that at least one aspect of a person's IQ can be improved by training a certain type of memory. Most IQ tests attempt to measure two types of intelligence--crystallized and fluid. Crystallized intelligence draws on existing skills, knowledge and experiences to solve problems by accessing information from long-term memory. Fluid intelligence, on the other hand, draws on the ability to understand relationships between various concepts, independent of any previous knowledge or skills, to solve new problems. The research shows this part of intelligence can be improved through memory training. Discover Magazine included this on its list of the top 100 science stories for 2008.

On the Threshold of a New World of Particle Physics: Large Hadron Collider
Located at the CERN laboratory near Geneva, Switzerland, the Large Hadron Collider (LHC) is the world's most powerful particle accelerator. The U.S. Department of Energy (DOE) and NSF invested a total $531 million in the construction of the accelerator, which scientists believe could help unlock extraordinary discoveries about the nature of the physical universe. NSF-supported researchers contributed to the design, construction, maintenance and operation of the two largest detectors-the Compact Muon Solenoid (CMS) and the A Toroidal LHC ApparatuS (ATLAS). On September 10, an international collaboration of scientists sent the first beam of protons zooming at nearly the speed of light around the LHC's 27-kilometer ring. The LHC attracted the interest of many mainstream publications; for example, it was Time Magazine's top scientific discovery for 2008.

But First, a Delay....
While the first beam tests were successful, an electrical malfunction a few days later brought start-up activities to a halt. Investigators concluded that a faulty electrical connection between two of the accelerator's magnets resulted in mechanical damage and release of helium from the magnet cold mass into the tunnel. Repairs and new protective measures are ongoing, and CERN has announced a restart date of late September 2009 for the beams, with proton collisions at low energies starting in late October.

Extra-solar Planets Directly Observed
Until 2008, the existence of planets outside our solar system were detected by indirect methods--orbiting planets causing a star to "wobble," or gravitational microlensing. But 2008 brought the first direct observations of extra-solar planets. Astronomers using the Gemini North telescope and W.M. Keck Observatory on Hawaii's Mauna Kea obtained the first-ever direct images identifying a multi-planet system around a normal star. The historic infrared images of an extra-solar multiple-planet system were made possible by adaptive optics technology used to correct in real time for atmospheric turbulence, the shimmering or blinking of starlight as it passes through the earth's atmosphere. And a Hubble Space Telescope team led by a University of California, Berkeley researcher has obtained the first optical image of a planet. Only 25 light years away, the Jupiter-size planet is like Neptune in that it sculpts the inner edge of a belt of comets and debris, the equivalent of our Kuiper belt. Science magazine named the exoplanet sightings as a runner up in its list of science breakthroughs for 2008.

They're Brilliant....Don't Just Take Our Word for It
In December 2008, NSF announced the 20 young scientists who received Presidential Early Career Awards for Scientists and Engineers (PECASE) for the 2007 competition. The award is the highest honor bestowed by the U.S. government on scientists and engineers in the early stages of promising independent research careers. PECASE nominees are chosen from junior researchers and faculty who received an NSF Faculty Early Career Development (CAREER) program award. The names of CAREER awardees are found on a number of prestigious lists. For example, in October, Popular Science magazine named its "Brilliant 10" Class of 2008, and four of them were past CAREER awardees, including University of Colorado at Bolder biomaterials engineer Kristi Anseth who also received NSF's Alan T. Waterman Award, the foundation's most prestigious honor for a young researcher, in 2004. In addition to the CAREER awardees, two other NSF-supported researchers made Popular Science's "Brilliant 10" list of young researchers to watch.

Biologists Learn Structure, Mechanism of a Powerful Molecular Motor in Virus
Researchers from Purdue University and the Catholic University of America have discovered the atomic structure of a powerful "molecular motor" that packages DNA into the head segment of some viruses during their assembly, an essential step in their ability to multiply and infect new host organisms. The virus in the study, called T4, is not a common scourge of people, but its host is the bacterium Escherichia coli (E. coli). T4 has been an important model system for studying virus mechanisms since the 1940s. The new findings could lead to sophisticated nanomachines. In addition, because a number of virus types (including the one that causes herpes) may possess a similar motor, the results may also assist pharmaceutical companies developing methods to sabotage virus machinery.
